First, an overview of example embodiments of the present invention will be described.

(1) Technical Issues

Mobile terminals (drone or the like) that perform flight according to information on a flight path received from a server or the like via a communication network have been widely known.

For example, PTL 1 discloses configuring of a flight route of a flight apparatus based on a radio resource that can be allocated to a flight apparatus (mobile terminal) by a base station.

Further, PTL 2 discloses the following: when an operation administrator determines that a flight of a drone according to a flight plan is impossible, instructing a business terminal that manages the drone to carry out emergency landing (landing at an unscheduled landing point; the landing point is, for example, a riverbed, a branch office of the business operator, or the like).

Further, PTL 3 discloses the following: when it is determined that a drone is in a state capable of flying for approximately at least several minutes, transmitting, to the drone, countermeasure instruction information for guiding the drone to a landing point to allow its landing.

However, for example, in the technique disclosed in PTL 2, for example, when a mobile terminal such as a drone cannot perform flight, for example, landing instruction at a landing point such as a riverbed, a branch office of a business operator, or the like is only performed for the mobile terminal. In other words, the techniques disclosed in the above-described patent literatures and the like including PTL 2 do not enable landing at an appropriate landing point in reaction to a change of an incident that may occur while the mobile terminal flies along a flight path.

One example object of the present example embodiment is to enable the mobile terminal to land at an appropriate landing point in reaction to a change of an incident that may occur while the mobile terminal flies along a flight path.

(2) Technical Features

In the present example embodiment, for example, a control apparatus acquires, according to a flight of a first mobile terminal performed based on a flight path to a first landing point, information on one or more second landing points associated with the flight path to the first landing point, and transmits the information on the one or more second landing points to the first mobile terminal via a communication network.

In the present example embodiment, for example, a first mobile terminal receives, according to a flight of a first mobile terminal performed based on a flight path to a first landing point, information on one or more second landing points associated with the flight path to the first landing point via a communication network, and performs landing operation at a target scheduled point different from the first landing point according to the information on the one or more second landing points.

With this configuration, for example, the mobile terminal can land at an appropriate landing point in reaction to a change of an incident that may occur while the mobile terminal flies along a flight path.

Note that the technical features described above are merely a specific example of the example embodiments of the present invention, and as a matter of course, the example embodiments of the present invention are not limited to the technical features described above.

2. Configuration of System

With reference to FIG. 1, an example of a configuration of a system 1 according to the example embodiments of the present invention will be described. FIG. 1 is an explanatory diagram illustrating an example of a schematic configuration of the system 1 according to the example embodiment of the present invention. With reference to FIG. 1, the system 1 includes a control apparatus 100, mobile terminals 200a, 200b, and 200c (collectively also referred to as “mobile terminal 200”), mobile communication networks 300a, 300b, and 300c (collectively referred to as “mobile communication network 300”) that are respectively managed by a plurality of mobile communication carriers, network exposure functions (NEFs) 410a, 410b, and 410c,an application server apparatus 420, and an artificial intelligence processing server apparatus 430.

(Control Apparatus 100)

For example, the control apparatus 100 performs communication with the mobile terminal 200 via the NEF 410 and the mobile communication network 300. Note that the control apparatus 100 may perform communication with the mobile terminal 200 by using not only the mobile communication network 300 managed by the mobile communication carrier but also any radio communication means (a satellite communication network or the like).

(Mobile Terminal 200)

The mobile terminal 200 is, for example, a terminal apparatus such as an unmanned drone and a manned drone that performs flight according to information on a flight path received from the control apparatus 100. For example, each of the mobile terminals 200a, 200b, and 200c may perform communication with any of the mobile communication networks 300a, 300b, and 300c.

(Mobile Communication Network 300)

The mobile communication network 300 is a network managed by respective mobile communication carriers as described above, for example, and is a network conforming to standards/specifications of the Third Generation Partnership Project (3GPP). More specifically, for example, the mobile communication network 300 may be a network conforming to standards/specifications of LTE/LTE-Advanced and/or System Architecture Evolution (SAE). Alternatively, the mobile communication network 300 may be a network conforming to standards/specifications of the fifth generation (5G)/New Radio (NR). The mobile communication network 300 includes, for example, a radio access network 310, and wirelessly performs communication with the mobile terminal 200 through the radio access network 310. As a matter of course, the mobile communication network 300 includes a core network higher than the radio access network 310.

(Application Server Apparatus 420 and Artificial Intelligence Processing Server Apparatus 430)

The application server apparatus 420 and the artificial intelligence processing server apparatus 430 provide various pieces of information to the control apparatus 100. For example, the application server apparatus 420 may execute a flight application that a business operator managing the mobile terminal 200 performs remote operation. The application server apparatus 420 may, for example, acquire weather information of a flight airspace managed by the control apparatus 100, and provide the weather information to the control apparatus 100 at any timing.

The processing section 130 may be implemented with one or more processors. The information acquisition section 131, the first communication processing section 133, and the second communication processing section 135 may be implemented with the same processor or may be implemented with separate processors.

Concrete operations of the first communication processing section 241, the second communication processing section 243, the notification processing section 245, and the control section 247 will be described later in detail.

For example, the processing section 240 (first communication processing section 241) communicates with the mobile communication network 300 via the radio communication section 210.

The program may be a program for causing the processor(s) to execute the operations of the processing section 130 (operations of the information acquisition section 131, the first communication processing section 133, and/or the second communication processing section 135).

<3.3. Technical Features>

With reference to FIG. 4 to FIG. 10, technical features of the first example embodiment will be described.

According to the first example embodiment, the control apparatus 100 (information acquisition section 131) acquires, according to a flight of the first mobile terminal (for example, the mobile terminal 200a) performed based on a flight path to a first landing point, information on one or more second landing points associated with the flight path to the first landing point. The control apparatus 100 (first communication processing section 133) transmits the information on the one or more second landing points to the first mobile terminal (for example, the mobile terminal 200a) via the communication network (for example, the mobile communication network 300).

According to the first example embodiment, the first mobile terminal (for example, the first communication processing section 241 of the mobile terminal 200a) receives, according to a flight of the first mobile terminal (for example, the mobile terminal 200a) performed based on the flight path to the first landing point, information on one or more second landing points associated with the flight path to the first landing point via the communication network (for example, the mobile communication network 300). The first mobile terminal (for example, the control section 247 of the mobile terminal 200a) performs landing operation at a target scheduled point different from the first landing point according to the information on the one or more second landing points.

FIG. 4 is a diagram for schematically describing technical features of the first example embodiment. With reference to FIG. 4, for example, when it is expected that the mobile terminal 200a performing flight to a first landing point 41 is to pass through a thunder forecast area 42, the control apparatus 100 (information acquisition section 131) transmits, to the mobile terminal 200a, information (information transmitted by an arrow 45 in FIG. 4) on second landing points 43 and 44 associated with a flight path R to the first landing point 41. Subsequently, the mobile terminal 200a starts landing operation at one of the second landing points 43 and 44, and can thereby avoid passing through the thunder forecast area 42.

(1) The Flight Path to the First Landing point

The flight path to the first landing point is, for example, a flight path configured by the control apparatus 100 according to a flight request from the first mobile terminal (for example, the mobile terminal 200a), a management server (for example, the application server apparatus 420) that manages the first mobile terminal (for example, the mobile terminal 200a), or the like.

For example, a flight path from a take-off scheduled point of the first mobile terminal (for example, the mobile terminal 200a) to the first landing point is configured for the control apparatus 100. When the flight path is configured by the control apparatus 100, information on the flight path is transmitted to the first mobile terminal (for example, the mobile terminal 200a) via the mobile communication network 300. The mobile communication network 300 with which the first mobile terminal (for example, the mobile terminal 200a) wirelessly communicates configures a radio resource for the flight of the first mobile terminal (for example, the mobile terminal 200a).

FIG. 5 is an explanatory diagram for describing an example of flight operation of the first mobile terminal (for example, the mobile terminal 200a) based on the flight path to the first landing point. With reference to FIG. 5, for example, the radio access network 310 allocates a radio resource for the mobile terminal 200a to fly along the flight path R to four radio stations 311, 312, 313, and 314 whose coverage areas are configured on a flight path 53 from a take-off scheduled point 51 to a first landing point 52. The radio resource is, specifically, a frequency time domain resource secured by each of the radio stations 311, 312, 313, and 314 to perform radio communication with the mobile terminal 200a. For the mobile terminal 200a, each of the radio stations 311, 312, 313, and 314 secures as many frequency time domain resources as necessary for the mobile terminal 200a to perform flight while the mobile terminal 200a exists in the coverage area, for example. In this manner, as illustrated in FIG. 5, the mobile terminal 200a transmits and/or receives information (for example, position information of the mobile terminal 200a, remaining battery information of the mobile terminal 200a, instruction information from the control apparatus 100, or the like) with the control apparatus 100 via each of the radio stations in order of the radio stations 311, 312, 313, and 314, and can thereby perform flight along the flight path 53.

Configuration of Flight Path Based on Zone

The flight path for flying to the first landing point may be configured based on a plurality of zones capable of identifying a three-dimensional space in common among the mobile communication networks 300a, 300b, and 300c managed by a plurality of mobile communication carriers performing radio communication with the mobile terminal (for example, the mobile terminals 200a, 200b, and 200c).

FIG. 6 is a diagram illustrating a specific example of a plurality of zones 61 allocated by a flight airspace 60 managed by the control apparatus 100. The zone 61 is, for example, a three-dimensional space identified by latitude, longitude, and altitude. As a specific example, a region in which the flight airspace 60 is identified with (X+3) minutes from 35 degrees X minutes north latitude, (Y+7) minutes from 139 degrees Y minutes east longitude, and altitude of 150 m or less is assumed (X and Y are any positive number). In this case, for example, the control apparatus 100 allocates a total of 64 zones. In other words, four different zones are allocated in the unit of minutes in the latitude direction, eight different zones are allocated in the unit of minutes in the longitude direction, and two different zones are allocated in the unit of 75 m in the altitude direction.

For example, a zone 61a at 35 degrees X minutes north latitude, 139 degrees (Y+7) minutes east longitude, and altitude of 0 to 75 m is considered. In this case, adjacent zones in the latitude direction and the altitude direction correspond to zones 61b and 61c, respectively.

The control apparatus 100 manages the number of mobile terminals that can pass per unit time for each zone 61, and can thereby appropriately manage the flight path of each of the mobile terminals (for example, the mobile terminals 200a, 200b, and 200c) communicated and connected with different mobile communication networks 300.

The control apparatus 100 may manage the number of mobile terminals that can pass per unit time based on the flight direction of the mobile terminals for each zone 61. For example, when the mobile terminals passing through the zone 61 fly and pass from every direction, the number of mobile terminals that can pass per unit time may be configured to a relatively small number (for example, a number smaller than a predetermined threshold). In contrast, in a case of a flight in which the directions of the mobile terminals passing through the zone 61 are fixed, for example, all of the mobile terminals fly from the south and head for the north, the number of mobile terminals that can pass per unit time may be configured to a relatively large number (for example, a number equal to or larger than the predetermined threshold).

The control apparatus 100 may manage the number of mobile terminals that can pass per unit time based on a flight speed of the mobile terminals for each zone 61. For example, the mobile terminals passing through the zone 61 pass at a low speed, for example, 30 km/H, the number of mobile terminals that can pass per unit time may be configured to a relatively large number (for example, a number equal to or larger than a predetermined threshold). In contrast, when the mobile terminals passing through the zone 61 pass at a high speed, for example 100 km/H, the number of mobile terminals that can pass per unit time may be configured to a relatively small number (for example, a number smaller than the predetermined threshold).

Information on the zone 61 is notified from the control apparatus 100 to each of the mobile communication networks 300. The example illustrated in FIG. 6 is considered. As information on the zone 61, the control apparatus 100 notifies each of the mobile communication networks 300 of information on the flight airspace 60 identified with latitude, longitude, and altitude, the number (for example, 64 ) of zones allocated in the flight airspace 60, and an allocation standard (the unit of minutes, the unit of the altitude of 75 m, or the like).

As the information on the zone 61, the control apparatus 100 may transmit information (identifiers of the zones or the like) for identifying each of the zones 61 in the flight airspace 60 to each of the mobile communication networks 300.

Each of the mobile communication networks 300 associates, for example, the zone 61 notified from the control apparatus 100 with a tracking area managed for each of the mobile communication networks 300 in advance, and can thereby easily identify the radio station whose coverage area is present on the flight path to the first landing point. The zone 61 may correspond to one tracking area, or may correspond to a plurality of tracking areas. A plurality of zones 61 may correspond to one tracking area.

(2) The Information on the Second Landing Point

The information on the one or more second landing points is, for example, associated with the flight path for flying to the first landing point in the following example aspects.

Association Based on Distance

For example, the one or more second landing points may be present at or within a predetermined distance (for example, 1 km from the flight path) from the flight path for flying to the first landing point. With the one or more second landing points being present at or within a predetermined distance from the flight path as described above, the first mobile terminal (for example, the mobile terminal 200a) can be caused to promptly land in reaction to a change of an incident that has occurred on the flight path (for example, a change of a weather condition that may suddenly occur or the like).

Association Based on Zone

For example, when the flight path is configured based on the zone as described above, the one or more second landing points may be point(s) identified based on one or more zones to which the flight path to the first landing point belongs. Specifically, the one or more second landing points may be, for example, identified as being present immediately under the same zone as that to which the flight path belongs or its adjacent zone. With this, the control apparatus 100 can, for example, manage the number of mobile terminals to be caused to land at the one or more second landing points for each zone.

Specific Example of Second Landing Point Information

The one or more second landing points may be information acquired according to information on an operation state of the first mobile terminal (for example, the mobile terminal 200a). Specifically, the information on the operation state of the first mobile terminal (for example, the mobile terminal 200a) is, for example, information, such as remaining battery, internal temperature, and power consumption, that may be transmitted from the first mobile terminal (for example, the mobile terminal 200a). In other words, the control apparatus 100 (for example, the information acquisition section 131) configures the second landing point according to the remaining battery that may be transmitted from the first mobile terminal (for example, the mobile terminal 200a), for example, and thereby acquires the second landing point. For example, a point closer to the flight path is preferentially configured for the second landing point as the remaining battery of the first mobile terminal (for example, the mobile terminal 200a) is less.

The one or more second landing points may be information acquired according to information on a condition of the flight path to the first landing point. Specifically, the information on the condition of the flight path to the first landing point is, for example, weather information provided from the application server apparatus 420 or the like. In other words, the control apparatus 100 may configure the second landing point suitable for the mobile terminal 200, based on weather information provided from the application server apparatus 420 or the like. For example, the second landing point may exclude the thunder forecast area identified based on the weather information from the configuration of the second landing point. For example, the second landing point may be preferentially configured in view of wind direction and wind speed identified based on the weather information.

The one or more second landing points may be information acquired according to information on a type of the first mobile terminal (for example, the mobile terminal 200a). Specifically, the information on the type of the first mobile terminal (for example, the mobile terminal 200a) corresponds to, for example, an attribute classified according to an application (a delivery service, a taxi) or the like of the mobile terminal. As an example, when there are two types, i.e., a delivery service and a taxi, the control apparatus 100 (for example, the information acquisition section 131) may configure the second landing point as follows, for example, according to the information on the type of the mobile terminal 200 that may be transmitted from the mobile terminal 200. For example, when the type of the mobile terminal 200 corresponds to the “delivery service”, a relatively narrow place such as a vacant lot may be configured as the second landing point. In contrast, when the type of the mobile terminal 200 corresponds to the “taxi”, the second landing point may be configured only to a relative wide place such as a ground of a school.

Plurality of Second Landing Points

The information on the one or more second landing points may be information on a plurality of second landing points. In this case, for example, the first mobile terminal (for example, the control section 247 of the mobile terminal 200a) determines the landing scheduled point out of the plurality of second landing points, based on the current position of the first mobile terminal (for example, the mobile terminal 200a). For example, the second landing point closest to the current position out of the plurality of second landing points may be determined as the landing scheduled point. When communication between the first mobile terminal (for example, the mobile terminal 200a) and the mobile communication network 300 is disconnected, for example, the first mobile terminal (for example, the control section 247 of the mobile terminal 200a) may determine that the second landing point located in a cell (cell provided by the radio station) with which the first mobile terminal (for example, the mobile terminal 200a) was last communicated as the landing scheduled point.

Priority

Regarding each of the second landing points, priority for the first mobile terminal (for example, the mobile terminal 200a) to preferentially land may be configured.

(Operation Performed by Control Apparatus 100)

For example, the information on the plurality of second landing points may include information indicating priority for the first mobile terminal (for example, the mobile terminal 200a) to preferentially land for each of the second landing points. In other words, the control apparatus 100 (first communication processing section 133) may transmit the information indicating the priority to the first mobile terminal (for example, the mobile terminal 200a).

In particular, the information indicating the priority may be information acquired according to the information on the type of the mobile terminal. For example, the control apparatus 100 (information acquisition section 131) may configure the priority according to the type of the first mobile terminal (for example, the mobile terminal 200a), and thereby acquire the information indicating the priority.

For example, when the type of the first mobile terminal (for example, the mobile terminal 200a) corresponds to the “delivery service”, the priority may be configured as follows. For example, as the second landing point corresponding to the first priority, a private place, such as the property of a company managing the first mobile terminal (for example, the mobile terminal 200a), is configured. As the second landing point corresponding to the second priority, for example, a public place, such as a park and a riverbed, is configured. As the second landing point corresponding to the third priority, for example, a place in which the first mobile terminal (for example, the mobile terminal 200a) can land even though articles to be delivered are damaged or lost, such as a river, the ocean, or in the mountains, is configured.

When the type of the first mobile terminal (for example, the mobile terminal 200a) corresponds to the “taxi”, the priority may be configured as follows. For example, as the second landing point corresponding to the first priority, a private place, such as the property of a company managing the first mobile terminal (for example, the mobile terminal 200a), is configured. As the second landing point corresponding to the second priority, a private place of an entity other than a company managing the first mobile terminal (for example, the mobile terminal 200a), such as a hospital and a heliport of a large building, is configured. As the second landing point corresponding to the third priority, for example, a public place such as a park and a riverbed, is configured. As the second landing point corresponding to the fourth priority, for example, a river, the ocean, in the mountains, or the like is configured. As the second landing point corresponding to the fifth priority, for example, a place allowing landing using a parachute is configured.

(Operation Performed by the First Mobile Terminal)

The priority is not necessarily configured by the control apparatus 100. For example, the first mobile terminal (control section 247 of the mobile terminal 200a) may configure the information indicating the priority, based on the type of the first mobile terminal.

(3) Instruction of Flight Cancellation

The control apparatus 100 (first communication processing section 133) may transmit information instructing cancelation of a flight of the first mobile terminal (for example, the mobile terminal 200a) performed based on the flight path to the first landing point to the first mobile terminal (for example, the mobile terminal 200a) via the communication network (for example, the mobile communication network 300).

More specifically, the control apparatus 100 transmits the information instructing cancellation of a flight to the first mobile terminal (for example, the mobile terminal 200a) via the communication network (for example, the mobile communication network 300), based on information on a condition of the flight path to the first landing point. Here, the information on the condition of the flight path to the first landing point is, for example, information provided from the application server apparatus 420, the artificial intelligence processing server apparatus 430, or the like, such as a change of weather that may suddenly occur on the flight path.

The information on the one or more second landing points may be included in the information instructing cancellation of a flight of the first mobile terminal (for example, the mobile terminal 200a). In this manner, the landing point suitable for promptly performing of landing operation after cancellation of the flight can be notified to the first mobile terminal (for example, the mobile terminal 200a).

When the first mobile terminal (for example, the control section 247 of the mobile terminal 200a) receives the information instructing cancellation of the flight of the first mobile terminal (for example, the mobile terminal 200a) from the control apparatus 100, the first mobile terminal starts landing operation at the landing scheduled point.

When the control apparatus 100 instructs cancellation of the flight, information on an emergency alert (for example, information on a weather change) or the like may be distributed from the radio access network (for example, the radio access network 310) present on a communication path between the control apparatus 100 and the first mobile terminal (mobile terminal 200a) to the first mobile terminal (for example, the mobile terminal 200a) and the mobile terminals (for example, the mobile terminals 200b and 200c) flying in the surrounding area by using the Public Warning System (PWS) or the Cell Broadcast Service (CBS). The PWS may be, for example, any one of the Earthquake and Tsunami Warning System (ETWS), the Commercial Mobile Alert System (CMAS), the Korean Public Alert System (KPAS), and EU Alert.

Operation Example FIG. 7 is a diagram for describing an example of a flow of the landing operation of the first mobile terminal according to the instruction of flight cancellation from the control apparatus 100. In the example illustrated in FIG. 7, for example, the first mobile terminal (mobile terminal 200a) is communicably connected to the control apparatus 100 via one of three radio access networks (RANs) 310a, 310b, and 310c in the mobile communication network 300.

First, with reference to FIG. 7, the control apparatus 100 transmits information instructing flight permission to the first mobile terminal (mobile terminal 200a) (S701). The information instructing the flight permission includes, for example, information indicating the flight path to the first landing point, radio information used by the first mobile terminal (mobile terminal 200a) for a flight along the flight path, and information on the plurality of second landing points.

Next, the control apparatus 100 starts communication for the first mobile terminal (mobile terminal 200a) to perform flight (S703). Next, the first mobile terminal (mobile terminal 200a) takes off from the current position and starts flight (S705).

Next, the control apparatus 100 transmits information instructing cancellation of the flight of the first mobile terminal (mobile terminal 200a) to the first mobile terminal (mobile terminal 200a) (S707). Note that, when a certain number of mobile terminals or more perform flight near the first mobile terminal (mobile terminal 200a), the control apparatus 100 may configure a predetermined standby time, based on hovering capability (for example, information that may be obtained from the remaining battery or the like) of the first mobile terminal (mobile terminal 200a). In this case, the control apparatus 100 may transmit the information instructing cancellation of the flight of the first mobile terminal (mobile terminal 200a) after the elapse of the standby time. When the control apparatus 100 instructs the first mobile terminal (mobile terminal 200a) to standby, it means that the first mobile terminal (mobile terminal 200a) exists in the zone in which the first mobile terminal (mobile terminal 200a) exists for scheduled time or longer. In order to secure safety of the entire flight region, the control apparatus 100 may perform instruction of cancellation of a flight or changes of a flight path to the mobile terminals in the zone as well as other zones.

The information instructing cancellation of the flight includes information on the plurality of second landing points, a change instruction on operation related to the flight, and a flight number normalized for each mobile terminal (flight management number managed by the control apparatus 100). Here, the information on the plurality of second landing points may be different from at least a part of the information on the second landing point transmitted at the time of flight permission.

Next, the first mobile terminal (mobile terminal 200a) determines the closest landing scheduled point, based on the current position and the plurality of second landing points (S709). Next, the first mobile terminal (mobile terminal 200a) starts transmission of a camera image to the application server apparatus 420 and performs landing by means of remote operation (S711). Subsequently, the first mobile terminal (mobile terminal 200a) arrives at the landing scheduled point (S713). When the mobile terminal (mobile terminal 200a) arrives at the landing scheduled point, the mobile terminal (mobile terminal 200a) may notify the control apparatus 100 of arrival point, arrival time, information of the mobile terminal (mobile terminal 200a) at the time of arrival, and information on the surroundings of the landing scheduled point.

According to the operation illustrated in FIG. 7 described above, the first mobile terminal (mobile terminal 200a) can land at an appropriate landing scheduled point according to the information instructing cancellation of the flight.

(4) Landing Operation according to Disconnection of Communication

For example, when communication via the communication network (mobile communication network 300) by the mobile terminal 200 is disconnected, the mobile terminal 200 (control section 247) may start landing operation at the landing scheduled point. Specifically, when communication with any network node present on a communication path between the mobile terminal 200 and the control apparatus 100 is disconnected, or when deterioration of radio quality in the mobile terminal 200 is detected, the mobile terminal 200 (control section 247) may start the landing operation at the landing scheduled point.

Operation Example

FIG. 8 is a diagram for describing an example of a flow of the landing operation of the first mobile terminal (mobile terminal 200a) according to disconnection of communication between the control apparatus 100 and the first mobile terminal (mobile terminal 200a). In the example illustrated in FIG. 8, for example, the first mobile terminal (mobile terminal 200a) is communicably connected to the control apparatus 100 via one of three radio access networks (RANs) 310a, 310b, and 310c in the mobile communication network 300.

First, with reference to FIG. 8, the control apparatus 100 transmits information instructing flight permission to the first mobile terminal (mobile terminal 200a) (S801). The information instructing the flight permission includes, for example, information indicating the flight path to the first mobile terminal (mobile terminal 200a), radio information used by the first mobile terminal (mobile terminal 200a) for a flight along the flight path, and information on the plurality of second landing points.

Next, the control apparatus 100 starts communication for the first mobile terminal (mobile terminal 200a) to perform flight (S803). Next, the first mobile terminal (mobile terminal 200a) takes off from the current position and starts flight (S805).

Next, the first mobile terminal (mobile terminal 200a) disconnects communication with the control apparatus 100 (S807). The disconnection of communication includes, for example, a failure of handover, detection of a radio link failure (RLF), failure of reconnection (RRC re-establishment) of radio resource control (RRC), and the like with one or more radio stations with which the first mobile terminal (mobile terminal 200a) communicates.

Next, the first mobile terminal (mobile terminal 200a) determines the closest landing scheduled point, based on the current position and the plurality of second landing points, and performs landing toward the landing scheduled point by means of autonomous operation (S809). Subsequently, the first mobile terminal (mobile terminal 200a) arrives at the landing scheduled point (S811).

According to the operation example illustrated in FIG. 8 described above, for example, the first mobile terminal (mobile terminal 200a) receives the information on the plurality of second landing points in advance before the communication with the control apparatus 100 is disconnected such as at the time of flight permission, and can thus appropriately perform landing based on the information on the plurality of second landing points.

(5) Landing Operation according to Inter-Terminal Communication

When communication via the communication network (for example, the mobile communication network 300) by the first mobile terminal (for example, the mobile terminal 200a) is disconnected, the first mobile terminal (for example, the notification processing section 245 of the mobile terminal 200a) may notify one or more second mobile terminals (for example, the mobile terminals 200b and 200c) of information on the landing scheduled point. Here, the one or more second mobile terminals (for example, the mobile terminals 200b and 200c) are, for example, mobile terminals that can perform inter-terminal communication with the first mobile terminal (for example, the mobile terminal 200a), and exist in, for example, the same cell as that of the first mobile terminal (for example, the mobile terminal 200a) or its adjacent cell or the same zone as that of the first mobile terminal (for example, the mobile terminal 200a) or its adjacent zone.

The first mobile terminal (for example, the second communication processing section 243 of the mobile terminal 200a) may receive, from the one or more second mobile terminals (for example, the mobile terminals 200b and 200c), information on the landing scheduled point at which the one or more second mobile terminals (for example, the mobile terminals 200b and 200c) perform landing. In this case, the first mobile terminal (for example, the control section 247 of the mobile terminal 200a) may change the landing scheduled point at which the first mobile terminal (for example, the mobile terminal 200a) perform landing according to the information on the landing scheduled point at which the one or more second mobile terminals (for example, the mobile terminals 200b and 200c) perform landing.

Specifically, when the landing scheduled point at which the one or more second mobile terminals (for example, the mobile terminals 200b and 200c) perform landing is the same as the landing scheduled point determined by the first mobile terminal (for example, the mobile terminal 200a) or is close thereto (at or within a predetermined distance), the first mobile terminal (for example, the control section 247 of the mobile terminal 200a) executes processing for avoiding collision with the one or more second mobile terminals (for example, the mobile terminals 200b and 200c).

For example, in order to avoid collision with the one or more second mobile terminals (for example, the mobile terminals 200b and 200c), for example, the first mobile terminal (for example, the mobile terminal 200a) shares information such as the priority of the mobile terminals configured in advance by the control apparatus 100 or the like, the priority of the mobile terminals generated by a random function or the like, and time required before landing performed by each mobile terminal, with the one or more second mobile terminals (for example, the mobile terminals 200b and 200c), and changes the landing scheduled point at which the first mobile terminal (for example, the mobile terminal 200a) performs landing through negotiation based on these pieces of information (transmission and/or reception of the information).

When the landing scheduled point is not a point but is a range having a certain area, the first mobile terminal (for example, the mobile terminal 200a) may change the landing scheduled point to a finer range through negotiation with the one or more second mobile terminals (for example, the mobile terminals 200b and 200c), and thereby configure the landing scheduled point at which the first mobile terminal (for example, the mobile terminal 200a) performs landing to a point different from the landing scheduled point of the second mobile terminal.

The first mobile terminal (for example, the mobile terminal 200a) may share the size of the terminals, the area of a place necessary for landing, or the like with the one or more second mobile terminals (for example, the mobile terminals 200b and 200c) through negotiation with the one or more second mobile terminals (for example, the mobile terminals 200b and 200c).

OPERATION EXAMPLE

Next, with reference to FIG. 9 and FIG. 10, the landing operation performed by the first mobile terminal (mobile terminal 200a) will be described.

First Operation Example

FIG. 9 is a diagram for describing a flow of a first operation example of the landing operation performed by the first mobile terminal (mobile terminal 200a). In the example illustrated in FIG. 9, for example, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) fly under control of the control apparatus 100. For example, the first mobile terminal (mobile terminal 200a) is communicably connected to the control apparatus 100 via the radio access network 310.

First, with reference to FIG. 9, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) each start a flight along the flight path under control of the control apparatus 100 (S901a, S901b, and S901c).

Next, when the communication established with the control apparatus 100 is disconnected (S903), for example, the first mobile terminal (mobile terminal 200a) determines the landing scheduled point, based on information on the second landing point (S905). Next, the first mobile terminal (mobile terminal 200a) notifies the second mobile terminals (mobile terminals 200b and 200c) flying in the surrounding area of information (landing information) on the landing scheduled point (S907). At substantially the same timing, the first mobile terminal (mobile terminal 200a) receives, from the second mobile terminals (mobile terminals 200b and 200c) flying in the surrounding area, the information on the landing scheduled point at which the second mobile terminals (mobile terminals 200b and 200c) perform landing.

An example of a communication method of the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) flying in the surrounding area will be described. When communication established with the control apparatus 100 is disconnected (S903), the first mobile terminal (mobile terminal 200a) performs securement of communication with the second mobile terminals (mobile terminals 200b and 200c) flying in the surrounding area. In this case, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) execute proximity communication. The first mobile terminal (mobile terminal 200a) may detect the second mobile terminals (mobile terminals 200b and 200c) by using the device discovery function defined by 3GPP. In addition, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) may communicate by using a unicast, groupcast, or broadcast communication method using the sidelink defined by 3GPP. In this case, the control apparatus 100 may enable proximity communication by notifying the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) of the same Group ID and/or Group IP multicast address and/or Temporary Mobile Group Identity (TMGI) and/or ProSe Group ID and/or ProSe Layer 2 Group ID.

Next, if there is no overlapping of the landing scheduled point, the first mobile terminal (mobile terminal 200a) continues landing, and if there is overlapping, the first mobile terminal (mobile terminal 200a) executes processing for avoiding collision and reselects the landing scheduled point (S909). Subsequently, the first mobile terminal (mobile terminal 200a) arrives at the landing scheduled point (S911).

According to the operation example illustrated in FIG. 9 described above, the first mobile terminal (mobile terminal 200a) can land at an appropriate landing scheduled point while avoiding collision or the like in cooperation with the second mobile terminals (mobile terminals 200b and 200c) flying in the surrounding area.

As an example alteration of the first operation example, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) may perform proximity communication during the flight. In this case, when communication established with the control apparatus 100 is disconnected (S903), the first mobile terminal (mobile terminal 200a) may perform communication with the control apparatus 100 via the second mobile terminals (mobile terminals 200b and 200c). This mode of communication may use Sidelink Communication via ProSe UE-to-Network Relay capability defined by 3GPP. In that case, the second mobile terminals (mobile terminals 200b and 200c) relays communication between the first mobile terminal (mobile terminal 200a) and the control apparatus 100.

When the first mobile terminal (mobile terminal 200a) and the control apparatus 100 become capable of communication via the second mobile terminals (mobile terminals 200b and 200c), landing by means of autonomous control of the first mobile terminal (mobile terminal 200a) as in the example illustrated in FIG. 9 need not necessarily be performed, and landing in cooperation with the control apparatus 100 as in the example illustrated in FIG. 7 may be performed.

Second Operation Example

FIG. 10 is a diagram for describing a flow of a second operation example of the landing operation performed by the first mobile terminal (mobile terminal 200a). In the example illustrated in FIG. 10, for example, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) fly under control of the control apparatus 100. For example, the first mobile terminal (mobile terminal 200a) is communicably connected to the control apparatus 100 via the radio access network 310.

First, with reference to FIG. 10, the first mobile terminal (mobile terminal 200a) and the second mobile terminals (mobile terminals 200b and 200c) each start a flight along the flight path under control of the control apparatus 100 (S1001a, S1001b, and S1001c).

Next, the first mobile terminal (mobile terminal 200a) and the second mobile terminal (mobile terminal 200c) disconnect the communication established with the control apparatus 100 (51003a and 51003c).

Next, the first mobile terminal (mobile terminal 200a) and the second mobile terminal (mobile terminal 200c) each determine the landing scheduled point (51005a and 1005c). Next, the first mobile terminal (mobile terminal 200a) and the second mobile terminal (mobile terminal 200c) notify the mobile terminals flying in the surrounding area of information (landing information) on the landing scheduled point (S1005a and 1005c).

Next, if there is no overlapping of the landing scheduled point, the first mobile terminal (mobile terminal 200a) and the second mobile terminal (mobile terminal 200c) continue landing, and if there is overlapping, the first mobile terminal (mobile terminal 200a) and the second mobile terminal (mobile terminal 200c) execute processing for avoiding collision and reselect the landing scheduled point (S1009a and S1009c). Subsequently, the first mobile terminal (mobile terminal 200a) and the second mobile terminal (mobile terminal 200c) each arrive at the landing scheduled point (S1011a and S1011c).

According to the operation example illustrated in FIG. 10 described above, the first mobile terminal (mobile terminal 200a) can land at an appropriate landing scheduled point while avoiding collision or the like in cooperation with the second mobile terminal (mobile terminal 200c) performing landing operation to land at the surrounding area.

(6) Example Alterations

According to the first example embodiment, for example, the specific examples described above are not restrictive, and various alterations can be made.

For example, when all of the mobile terminals to perform control perform communication with specific mobile communication networks 300 or the like, the control apparatus 100 need not be located outside of each of the mobile communication networks 300, and may be, for example, a network node inside of a specific mobile communication network 300.

For example, the first mobile terminal (for example, the mobile terminal 200a) may issue a warning sound to the landing scheduled point while landing at the landing scheduled point. Whether or not the warning sound is issued may be, for example, configured for each of the second landing points being candidates for the landing scheduled point.

For example, when the first mobile terminal (for example, the mobile terminal 200a) lands using a parachute, the control apparatus 100 may notify, before the landing, a public safety answering point (PSAP) such as a nearby police station and fire station that the first mobile terminal (for example, the mobile terminal 200a) is to perform landing.

In addition, when the first mobile terminal (for example, the mobile terminal 200a) determines that the first mobile terminal (for example, the mobile terminal 200a) cannot land at the second landing point, the first mobile terminal (for example, the mobile terminal 200a) may select an alternative path different from the first flight path and may fly in the alternative path without performing landing. When the first mobile terminal (for example, the mobile terminal 200a) detects an RLF (or HO failure, RRC reconnection failure), the first mobile terminal (for example, the mobile terminal 200a) may attempt connection to a predetermined cell. The predetermined cell may be any one of a cell closest to the current position, a cell (cell provided by the radio station) with which the first mobile terminal (for example, the mobile terminal 200a) was last communicated, and a cell based on information on the alternative path stored (acquired) in advance. For example, the information on the alternative path may be received when flight permission is instructed from the control apparatus 100. The first mobile terminal (for example, the mobile terminal 200a) may report information on a new flight path including at least the alternative path to the control apparatus 100. In addition, the control apparatus 100 may transmit new flight path information to the first mobile terminal (for example, the mobile terminal 200a) in response to reception of the information on the new flight path. In this case, the first mobile terminal (for example, the mobile terminal 200a) may receive the new flight path information.

4. Second Example Embodiment

Next, with reference to FIG. 11, a second example embodiment of the present invention will be described. The above-described first example embodiment is a concrete example embodiment, whereas the second example embodiment is a more generalized example embodiment.

The information acquisition section 511 and the communication processing section 513 may be implemented with the same processor or may be implemented with separate processors. The memory may be included in the one or more processors or may be provided outside the one or more processors.

The control apparatus 500 may include a memory configured to store a program (instructions) and one or more processors that can execute the program (instructions). The one or more processors may perform operations of the information acquisition section 511 and the communication processing section 513 by executing the program. The program may be a program for causing the processor(s) to execute the operations of the information acquisition section 511 and the communication processing section 513.

<4.3. Configuration of First Mobile Terminal 600>
